Configuration

Important Note: This chart is not compatible with Helm 2. Please use Helm 3.6+ with this chart.

The chart is highly customizable using Helm configuration values. Each value has a default tuned for an optimal getting started experience with Vault. Before going into production, please review the parameters below and consider if they're appropriate for your deployment.

  • global - These global values affect multiple components of the chart.

    • enabled (boolean: true) - The master enabled/disabled configuration. If this is true, most components will be installed by default. If this is false, no components will be installed by default and manually opting-in is required, such as by setting server.enabled to true.

    • imagePullSecrets (array: []) - References secrets to be used when pulling images from private registries. See Pull an Image from a Private Registry for more details. May be specified as an array of name map entries or just as an array of names:

      imagePullSecrets:
  - name: image-pull-secret
# or
imagePullSecrets:
  - image-pull-secret

    • tlsDisable (boolean: true) - When set to true, changes URLs from https to http (such as the VAULT_ADDR=http://127.0.0.1:8200 environment variable set on the Vault pods).

    • externalVaultAddr (string: "") - External vault server address for the injector and CSI provider to use. Setting this will disable deployment of a vault server. A service account with token review permissions is automatically created if server.serviceAccount.create=true is set for the external Vault server to use.

    • openshift (boolean: false) - If true, enables configuration specific to OpenShift such as NetworkPolicy, SecurityContext, and Route.

    • psp - Values that configure Pod Security Policy.

      • enable (boolean: false) - When set to true, enables Pod Security Policies for Vault and Vault Agent Injector.

      • annotations (dictionary: {}) - This value defines additional annotations to add to the Pod Security Policies. This can either be YAML or a YAML-formatted multi-line templated string.

        annotations:
  seccomp.security.alpha.kubernetes.io/allowedProfileNames: docker/default,runtime/default

If this isn't specified, then the pods won't request any specific amount of resources, which limits the ability for Kubernetes to make efficient use of compute resources.
      Setting this is highly recommended.

      resources:
  requests:
    memory: '256Mi'
    cpu: '250m'

    • certs - The certs section configures how the webhook TLS certs are configured. These are the TLS certs for the Kube apiserver communicating to the webhook. By default, the injector will generate and manage its own certs, but this requires the ability for the injector to update its own MutatingWebhookConfiguration. In a production environment, custom certs should probably be used. Configure the values below to enable this.

      • secretName (string: "") - secretName is the name of the Kubernetes secret that has the TLS certificate and private key to serve the injector webhook. If this is null, then the injector will default to its automatic management mode.

      • caBundle (string: "") - The PEM-encoded CA public certificate bundle for the TLS certificate served by the injector. This must be specified as a string and can't come from a secret because it must be statically configured on the Kubernetes MutatingAdmissionWebhook resource.

    • ha - This configures ha mode for the Vault server.

      • enabled (boolean: false) - Enables ha mode for the Vault server. This mode uses a highly available backend storage (such as Consul) to store Vault's data. By default this is configured to use Consul Helm. For a complete list of storage backends, see the Vault documentation.

      • updatePartition (int: 0) - If an updatePartition is specified, all Pods with an ordinal that is greater than or equal to the partition will be updated when the StatefulSet’s .spec.template is updated. If set to 0, this disables partition updates. For more information see the official Kubernetes documentation.

      • config (string or object: "{}") - A raw string of extra HCL or JSON configuration for Vault servers. This will be saved as-is into a ConfigMap that is read by the Vault servers. This can be used to add additional configuration that isn't directly exposed by the chart. If an object is provided, it will be written as JSON.

      # ExtraConfig values are formatted as a multi-line string:
config: |
  ui = true
  api_addr = "http://POD_IP:8200"

  }

  storage "consul" {
      path = "vault/"
      address = "HOST_IP:8500"
  }

      This can also be set using Helm's --set flag (vault-helm v0.1.0 and later), using the following syntax:

If you need to set this to 0, you will need to add a --set 'server.disruptionBudget.maxUnavailable=0' flag to the helm chart installation command because of a limitation in the Helm templating language.

    • statefulSet - This configures settings for the Vault Statefulset.

      • annotations (dictionary: {}) - This value defines additional annotations to add to the Vault statefulset. This can either be YAML or a YAML-formatted multi-line templated string.

  • serverTelemetry - Values the configure metrics and telemetry. Enabling these features requires setting the telemetry {} stanza in the Vault configuration. See the telemetry docs for more on the Vault configuration.

    Currently, this chart does not support authenticating to Vault's metrics endpoint, so the following telemetry {} block must be included in the listener "tcp" {} stanza of the Vault configuration:

  disable_hostname = true
}

    • serviceMonitor - Values that configure monitoring the Vault server

      • enabled (boolean: false) - When set to true, enable deployment of the Vault Server ServiceMonitor CustomResource. The Prometheus operator must be installed before enabling this feature.

    expr: vault_core_handle_request{quantile="0.5", namespace="mynamespace"} > 500
    for: 5m
    labels:
